如题，我上传的文件无法播放，没有缩略图。用videojs 报错：
Warning:  array_merge(): Argument #1 is not an array in /var/www/localhost/htdocs/piwigo/plugins/piwigo-videojs/admin/admin_sync.php on line 53



Notice:  Undefined index: output in /var/www/localhost/htdocs/piwigo/plugins/piwigo-videojs/admin/admin_sync.php on line 66



Warning:  array_merge(): Argument #1 is not an array in /var/www/localhost/htdocs/piwigo/plugins/piwigo-videojs/admin/admin_sync.php on line 78

谢谢！
